So ive got two basses both with wildly different output signals, one is super hot and the other is not. Instead of playing with volume knobs on the basses or my amps or volume pedals when i switch instruments, im looking for a boost/cut pedal. Just want one knob on the box, probably line level at 12pm and if you go counter clockwise its a cut, and when you go clock wise its a boost. im probably gonna have something like this made for me, but before i pull the trigger on that im wondering is there a pedal out there like this? i see tons of boosts and cuts by themselves, and i also see tons of versions with EQs and gains and all these other things i have no use for. just want one knob, backwards goes quieter, forwards gets louder. any ideas?
